Keepa tracks Amazon price and sales rank history for millions of products and displays charts right on Amazon product pages. Arbitrage sellers use it to see whether a price is stable, how often the item sells, and whether Amazon itself is on the listing.
Tactical Arbitrage (now part of the Threecolts Seller 365 bundle) scans retail websites and matches products to Amazon listings to find profitable price gaps automatically. It also has reverse search and wholesale manifest analysis. It is a heavy-duty tool for sellers committed to online arbitrage.
Retail and online arbitrage on Amazon live and die by data: sales rank, price history, Buy Box competition, fees and ungating restrictions. These tools range from free browser extensions to full research suites. Beginners usually start with one scanner app plus Keepa, and add a sourcing suite once they are consistently profitable. The deciding factors usually come down to each tool's standout strength (for Keepa: essential price and rank history; for Tactical Arbitrage: automates online arbitrage sourcing) weighed against its main drawback (steep learning curve versus expensive for beginners).
